(A) due to the cooling and lubrication of magnetic pump bearings are transported by the medium, it is absolutely forbidden air-to-run, while avoiding the power outage after the restart caused by the time-space operation. (B) is transported medium, if it contains solid particles, the pump inlet to be added to the filter: If containing ferromagnetic particles, the need to add magnetic filters. (C) The pump should be used in the ambient temperature should be less than 40 ℃, the motor temperature should not exceed 75 ℃. (D) was transported medium and its temperature should be allowed within the pump. Engineering plastic pump temperature (E) for the transmission fluid is easy to precipitate crystallization of the media, after use should be promptly cleaned, drain the pump effusion. (Vi) 1000 hours after the normal operation of the magnetic pump should be demolished inspection bearing and face ring wear and tear, and replace the consumable parts should not be reused.
